Climate Change Reconsidered II: Physical Science

Climate Change Reconsidered II: Physical Science (CCR-II is an independent, comprehensive, and authoritative report on the current state of climate science. It is the fourth in a series of scholarly reports produced by the Nongovernmental International Panel on Climate Change (NIPCC), an international network of climate scientists sponsored by three nonprofit organizations: Center for the Study of Carbon Dioxide and Global Change, Science and Environmental Policy Project (SEPP), and The Heartland Institute.

Previous volumes in the Climate Change Reconsidered series were published in 2008, 2009, and 2011.

Whereas the reports of the United Nations' Intergovernmental Panel on Climate Change (IPCC) warn of a dangerous human effect on climate, NIPCC concludes the human effect is likely to be small relative to natural variability, and whatever small warming is likely to occur will produce benefits as well as costs.

CCR-II consists of three parts: a Summary for Policy Makers (SPM), part one titled Physical Science, and part two titled Impacts, Adaptation, and Vulnerabilities. The SPM and Part One were released on September 17-18, 2013 in Chicago, Illinois USA. Part two will be released in the spring of 2014.
